Hi - I will be 16 Weeks on Friday and as you, I havnt felt anything yet(not that I know of) I have no symptoms and I was only sick once during the first few months but I just consider myself to be one of the lucky ones :-) I to often wonder whats going on in there because I cant feel anything and just feel "normal". Everything was fine at my scan but you do still worry that bit. I have mentioned all this to my midwife and she said its all normal and not to worry, so Im just enjoying being pregnant and looking forward to being a mum. Dont worry Im sure you will feel movement soon, I did ask my midwife when to expect feelings of the baby moving etc, and she said with it being my first could be anything up to or just over 20 weeks, or before I realise that it is the baby. Try not to worry and enjoy the "normal" feeling period, thats what I keep telling myself :-)
